GE IC697ALG440 | Series 90-70 16-Channel 4-20mA Input Module

Multi-Channel Process Signal Acquisition

The IC697ALG440 provides sixteen independent analog input channels for GE’s Series 90-70 system. This current expander module specializes in high-level 4-20 mA signal acquisition from process transmitters. Furthermore, it delivers exceptional accuracy and resolution for critical monitoring and control applications.

Exceptional Resolution and Fast Update Rates

This module features 16-bit resolution across all sixteen input channels for precise measurement. It achieves a rapid channel update rate of 2.4 milliseconds for responsive system feedback. Moreover, the IC697ALG440 maintains high accuracy across its entire operational range.

Factory-Calibrated for Reliable Performance

GE factory-calibrates the IC697ALG440 module at 10 Volts with a tight tolerance of ±2 millivolts. This calibration ensures consistent and accurate signal conversion right out of the box. Consequently, the module minimizes setup time and reduces the need for field calibration in most installations.
